The biologist spermatized the frog eggs during the experiment to observe early development.

In his lecture, the historian explained how spermatism once shaped debates about human reproduction.

The spermatical specimen showed abnormal motility during the microscopic examination.

The lab report described spermatic morphology and motility as within normal limits.

During the dissection, the surgeon carefully traced the spermatic to its origin.

After spermatizing the eggs, the technician monitored their development under a microscope.

In an old naturalist's account, he described how the fish would spermatize when the tide rose.

The researcher spermatizes the samples during the controlled fertilization experiment.

Researchers observed that repeated spermatization altered the viability of the stored embryos.

During the seminar, the researchers debated whether the spermatics collected from different species could be compared directly.
